SEPARABLE SKELETON STRUCTURE.

fiPEGIFICAIION forming part of Letters Patent No. 491,238, datedFebruary *7, 1893.

To 0,215 whom it may concern:

(is it known that I, HENRY PELLERIN DE LASTELLE, a citizen of the FrenchRepublic, residing at Paris, France, have invented certain Improvementsin Separable Skeleton Structures, of which the following is aspeciiication.

My invention relates to the class of frames for temporary structures,such as pavilions, tents, the, usually of metal, or of metal and woodcombined.

ihe invention will be fully described here inafter and its novelfeatures carefully defined in the claims.

In the accompanying drawings-Figure 1, is a side elevation of a skeletonstructure embodying my invention; Fig. 2, is an end view of the same,and Fig. 3, is a plan of the same. Figs. at, 5, 6, '7, 8, 9, 10, 11, 12,13, lit, 15, 16, 16 17, 17 18, 19, 2O, 21, 22, 23, 2i, and 26, aredetached detailviews, on a larger scale, illustrating the construction.

The principal figures represent a structure composed of ogival trussesconnected at their upper ends by a ridge-pole and at their bases bysoles or sole-beams, the whole being stiffened by cross-beams or bars.The soles A, are made of angle iron, and are connected at theirextremities to flat bars B, which form the base finish at the ends ofthe structure. The body-trusses, O, are of I-iron, thehead orend-trusses, D, are of T-iron and the hiptrusses, E, are also of T-iron.The ridgepole, F, is of wood, and is connected to the end-trusses D bythe means illustrated in Figs. Jr, 5, t3, 7 and 8. A metal plate, a(Fig. at), is riveted to one member of the truss D, and has at its apexor angle a fork, a, to receive the ridge-pole F. The plate a, is securedto the other member of the truss l) by means of a key 1), two views ofwhich are given in Figs. 5 and (I. This key is driven through a mortisec (Fig. d) in the plate a, and through a nearly corresponding mortise inthe flange of the other member of the truss D, whereby the parts aredrawn solidly and firmly together.

In order to secure the ridge pole F the more firmly in, place in thefork c, this pole is pro- 50 vided on one or both of its faces withpairs of cleats d, of angle iron, as seen in the side Serial No.437,996. (No model.)

and plan views of the ridge-pole, Figs. '7 and 8. The branch of the forka occupies the space between the pair of cleats and is embraced thereby,as indicated in Fig. 8.

The end-sole plates B, of fiat iron, have thelr extremities formed asindicated in Fig. 9, one extremity having it in an eye 6, and the otherextremity having on it a hookf. At the foot of each member of the trussE, is fixed a forked bracket, g, seen in side view, front view, and planin Figs. 10, 11, and 12, respect ively. A bolt h, (seen in Fig. 13) thesnug, 7a, of which engages a notch, 71 at the eye-end of the sole plateB, is engaged by the hookf, of the next sole plate, and also by the forkin the bracket g, on the truss, awing-nut, 7o, serving to clamp all ofthe parts solidly and firmly together when the bolt is in place.Thememhers of the hip-trusses E, are also secured to the sole plates Bin the manner described above, and in Figs. 10 and 11, the hip-truss 18shown. To the upper end of the member of the hip-truss, is riveted aplate Z, seen in side elevation in Fig. 1e and in plan in Fig. i5. Thisplate has a mortise, Z in a tenon on its end, to receive a key, Z lVhenthe tenon has been passed through an aperture in the endtruss, the key lis entered and driven in to draw the parts firmly together. The tenonson the plates Z also pass through apertures 1n the extremities of thetransom plates or bars G, seen in the principal views, thus securing alltogether, as will be readily understood.

Figs. 16 and 17, are sectional views, and Fig. 18, a side view,illustrating the manner of securing the intermediate bars H, to thetrusses D and E, of T-iron. The bar H has secured to each end a fiathook, m, which hooks into a square collar or, riveted to the 0 flangesof the truss at the proper height. After the hook m, is in place, a key0, with a snug, seen in Fig. 19, is inserted in registering mortises Zin the flange of the truss and the hooks m, and secures the parts firmlyto 5 gether.

Figs. 16 and 1'7 illustrate the mode of securing the bars H to themembers of the intermediate trusses O, which are of I-iron. In this casethe sleeve-n, is secured by a pin a, which passes through the web of thetruss member and is riveted down at its ends.

The ridge-pole F, is composed of several parts connected togetherendwise in the manner illustrated in Figs. 20, 21 and 22. A gain orrabbet K, (see plan, Fig. 22) is formed in the side of one extremity ofthe end portion of the ridge-pole, and similar gains are formed on bothends of the intermediate parts of the pole; and when the parts of thepole are aligned and the laps made, as seen in the cross section Fig.20,a key L, is driven through nearly registering apertures in. the partsand locked therein by a pin 1). This pin may be connected to the key bya chain. The key draws the sections of the ridge-pole firmly together.

The members of the intermediate trusses C, are secured together attheapex of the arch by the means illustrated in Figs. 23 and 2%, the formerbeing a side view and the latter a sectional plan. This construction issubstantially the same as that employed for the trusses D, except thatthe fork a to receive the ridgepole is omitted. The plates (1, may besecured to the member by bolts 1).

In order to establish a close connection between the ridge-p0le F andthe intermediate trusses C, keepers R, one of which is seen in Fig. 21,are formed on the underside of the ridge-pole by securing to the latterkeeper plates, 1", in pairs, as shown. hen the parts are assembled, theapex of each truss C, seen in Fig. 23,occupies one of the keepers R,seenin Fig. 2l,and is embraced by the keeper plates 7; and held in place bya key s,seen in Figs. 20 and 21,passed through apertures in the keeperplates below the truss. The foot of the member of the trussis secu redto the sole, A, by the means illustrated in Figs. 25 and 26, of whichthe former is a sectional elevation and the latter a sectional plan. Akeeper is formed on the sole A to receive the web of the member of thetruss, by securing to the sole two keeper plates, u, a; and thetrussmember is secured in the keeper by means of a key t, which passesthrough apertures or mortises in the upright flanges of the keeperplates and through a corresponding mortise in the web of thetrussmember. The key 6, is held in place by an auxiliary key 1), asshown.

My skeleton structure, which is adapted to be readily taken apart andput together, may be employed for any purpose where a structure capableof holding people or goods is required, as at fairs, expositions, 850.,or for a hospital. IVhen taken to pieces-its parts will pack closely forshipment. It may vary in form from the embodiment illustrated, and itmay be covered with canvas or other mate rial. The form illustrated iswell suited for canvas.

Having thus described my invention, I claim 1.
